README.md

tox aims to automate and standardize testing in Python. It is part of a larger vision of easing the packaging, testing and release process of Python software (alongside pytest and devpi).

tox is a generic virtual environment management and test command line tool you can use for:

• checking your package builds and installs correctly under different environments (such as different Python implementations, versions or installation dependencies),
• running your tests in each of the environments with the test tool of choice,
• acting as a frontend to continuous integration servers, greatly reducing boilerplate and merging CI and shell-based testing.

Please read our user guide for an example and more detailed introduction, or watch this YouTube video that presents the problem space and how tox solves it.

Welcome to the tox automation project¶

tox aims to automate and standardize testing in Python. It is part of a larger vision of easing the packaging, testing and release process of Python software.

What is tox?¶

tox is a generic virtualenv management and test command line tool you can use for:

• checking your package installs correctly with different Python versions and interpreters
• running your tests in each of the environments, configuring your test tool of choice
• acting as a frontend to Continuous Integration servers, greatly reducing boilerplate and merging CI and shell-based testing.

Basic example¶

First, install tox with pip install tox . Then put basic information about your project and the test environments you want your project to run in into a tox.ini file residing right next to your setup.py file:

# content of: tox.ini , put in same dir as setup.py [tox] envlist = py26,py27 [testenv] deps=pytest # install pytest in the venvs commands=pytest # or 'nosetests' or . 

You can also try generating a tox.ini file automatically, by running tox-quickstart and then answering a few simple questions.

To sdist-package, install and test your project against Python2.6 and Python2.7, just type:

and watch things happening (you must have python2.6 and python2.7 installed in your environment otherwise you will see errors). When you run tox a second time you’ll note that it runs much faster because it keeps track of virtualenv details and will not recreate or re-install dependencies. You also might want to checkout tox configuration and usage examples to get some more ideas.

Current features¶

• automation of tedious Python related test activities
• test your Python package against many interpreter and dependency configs

• automatic customizable (re)creation of virtualenv test environments
• installs your setup.py based project into each virtual environment
• test-tool agnostic: runs pytest, nose or unittests in a uniform manner
